[Prasanta Sadhukhan]

> Please review a test fix for an issue seen failing in mach5 testing although it is not reproducible locally.
> The issue seems to stem from the fact that the test was been run as headless test although it requires to create UI
> class like ComponentUI which is needed for painting, layout calculations etc and therefore it fails citing
> _no ComponentUI class for:
> javax.swing.JButton[,0,0,0x0,invalid,alignmentX=0.0,alignmentY=0.0,border=,flags=0,maximumSize=,minimumSize=,preferredSize=,defaultIcon=,disabledIcon=,disabledSelectedIcon=,margin=null,paintBorder=true,paintFocus=true,pressedIcon=,rolloverEnabled=false,rolloverIcon=,rolloverSelectedIcon=,selectedIcon=,text=Probably,defaultCapable=true]_
> Modified the test to mark it as headful.
> Mach5 job was run for several iteration on all 3 platforms. Link in JBS
